Which of the following option is correctly matched ?

Options

A. `S_3O_9` , contains no S-S linkage
B. `S_2O_6^(2-)` , contains -O-O-linkage
C. `(HPO_3)_3`, contains P-P linkage
D. `S_2O_8^(2-)` , contains S-S linkage

Explanation

To determine which of the given options is correctly matched, we will analyze each compound and its corresponding structure to identify any specific linkages mentioned in the options.

### Step-by-Step Solution:

1. **Analyze S3O9**:
- **Chemical Name**: Sulfur trioxide trimer.
- **Structure**: The structure consists of three sulfur atoms and nine oxygen atoms. The linkages present are S-O-S, indicating that there are no S-S linkages.
- **Conclusion**: The statement that S3O9 contains no S-S linkage is **correct**.

2. **Analyze S2O6^2-**:
- **Chemical Name**: Dithionate.
- **Structure**: The structure contains two sulfur atoms and six oxygen atoms. The linkages present are S-O, but there are no O-O linkages.
- **Conclusion**: The statement that S2O6^2- contains O-O linkage is **incorrect**.

3. **Analyze HPO3 (thrice)**:
- **Chemical Name**: Cyclotrimetaphosphoric acid.
- **Structure**: The structure consists of phosphorus and oxygen atoms with P-O-P linkages. There are no P-P linkages present.
- **Conclusion**: The statement that HPO3 contains P-P linkage is **incorrect**.

4. **Analyze S2O8^2-**:
- **Chemical Name**: Peroxydisulphate or persulphate ion.
- **Structure**: The structure has two sulfur atoms and eight oxygen atoms. The linkages present are S-O, and there are no S-S linkages.
- **Conclusion**: The statement that S2O8^2- contains S-S linkage is **incorrect**.

### Final Conclusion:
The only correct match is for **S3O9**, which contains no S-S linkage.
